Tunnel entering construction method suitable for permanent and temporary combination of high and steep thick-layer accumulation body side slope
The invention discloses a permanent and temporary combined tunnel entering construction method suitable for a high and steep thick-layer accumulation body side slope. The method comprises the steps of ground surface cleaning, construction of a catchwater outside a tunnel and related slope protection, construction of a tunnel portal wall and wall back backfilling, construction of a large pipe shed and construction of a concealed tunnel. The tunnel portal structure construction and the tunnel entering measure are combined, disturbance to the existing side and upward slope is reduced, and the construction safety is improved; temporary protection is combined with a permanent structure, so that the economical efficiency of construction is improved; and under the permanent and temporary combination mode, the existing surface ecological damage is reduced, and the greenness of the construction mode is improved.
本发明公开了一种适用于高陡厚层堆积体边坡永临结合的隧道进洞施工方法，包括地表清理→施作洞外截水沟及相关坡面防护→施作洞门墙、墙背回填→施作大管棚→施作暗洞；本发明洞门结构施工与进洞措施结合，降低对既有边仰坡的扰动，提升建造的安全性；临时防护与永久结构相结合，提升建造的经济性；永临结合方式下，降低既有地表生态破坏，提升建造模式的绿色性。
